changedetection.io

changedetection.io is Apache-2.0-licensed software for staying up to date with changes to content published on websites. It follows website content changes and helps users remain informed when that content is updated. The program is intended for anyone who needs to monitor changing web pages, with its purpose centered specifically on tracking updates to website content. For this task, changedetection.io can serve as an open source replacement for the paid product Zapier. Its main limitation is its narrow focus: changedetection.io is designed for monitoring website content changes, not presented as a feature-for-feature replacement for every use of Zapier. It is therefore most suitable when the automation you need is to follow changes on websites and stay informed as their content is updated.
